Ola Mae Barker, executrix, Birmingham, Mich, assignor to Penn Metal Company, Inc., Boston, Mass., a corporation of Delaware Filed Sept. 23, 1958, S'er. N0. 765,695 AGlaims. ..(Cl.:50481) This invention relates to -a resilientclip formed'of a strip of sheet metal for use-and in combination with metal lathing and associated structure-for supporting a plaster wall.

Expanded metal or wire mesh lathing and also metal studding together with-associated parts formed of metal are used inthe building trade in'the formation of single and double wall partitions whichiare finished with plaster. This invention'has as its'objects, in connection'wi-th'the use of such structure, to reduce its sound transmission characteristics, to increase its resistance to fire and to shock and to inhibit cracking of the plaster by improving it ability to absorb structural stresses and strains, to provide adjustability-of depth between the walls of double partitions and of distance between studding and in size of reinforcing panels .to accommodate pipes and vents and to increase the speed and economy of manufacture and installation.

Ordinarily, apart'ition'of this type is formed by erecting studding, which'may comprise the old fashioned wooden two by fours but which is preferably formed of steel members, then attaching to the studding a line of vertical cylindrical rods called pencil rods, then attaching to the pencil rods the panels of metal lathing, and then plastering over the lathing.

The above stated objectives are accomplished according to this invention by the use of resilient clip means by which the vertical pencil rods ands associated lathing are attached to the studding.

FIG. 11 is a view corresponding to FIG. 9 showing only a single clip and with the pencil rod tied to the clip as in FIG. '10. V

In the drawings, the double wall partition illustrated in FIG. 1 includes the plaster walls 1 and 2 between which are arranged the vertical steel studs S at the usual intervals. Each stud S has a web portion 3 and a pair of edge flange portions 4 which are at right angles to the web portion 3, and as best seen in FIG. 2, the web portion 3 has elongated holes-5 at spaced intervals for attaching ructure to be described, and may-also have cutout portions 6 for lightness of weight.

The reinforced plaster walls 1 and 2 are attached at a spaced distance to (the studs bythe resilient clip 10 of the invention. As shown in FIGS. Z-and 3, the clip 10 is made of a single strip of sheet metal and comprises a flat elongated flange portion 15, a backing portion 16 which is formed by a substantially degree bend 17 in the strip at one end of the=flange portion 15, a first intermediate portion 18 which is formed by a substantially degree bend '19 in the strip at the further end of the backing portion 16 and which is preferably sharply formed so that the first intermediate portion 18 lies closely adjacent the backing portion 16 for a purpose to be described, a second intermediate portion 20 formed by an enlarged substantially 180 degree bend 21 at the further end of the first intermediate portion 18 and a rod receiving portion 23 formed by a substantially 180 degreebend 24 at-the end of the second intermediate port-ion 20.

-In the wall structure illustrated in FIGS. 1 to 3 each resilient clip 10 is secured to a study S by means of a bolt B which passes through one of the holes 5 in the stud S and through an elongated slot 30 in the clip 10 which is formed lengthwise and slightly diagonally of the flangeportion 15 for adaptability and ease of installation with respect to various forms and sizes of studs. The clip 10 is fastened by the method of FIGS. 1 to 3 with its flange portion 15 and its backing portion 16 abutting the web 3 and the flange 4 respectively of the stud S and on the outside of the stud. When two or more clips 10 have been secured in vertical alignment along one edge of a. stud S, a cylindrical steel pencil rod 32 is inserted and retained in the bend 24 forming the rod receiving portion 23, which preferably has a slighly inwardly curved entrance portion 25 which serves to confine the pencil rod 32 under the receivingportion 23 of the clip. A series of pencil rods 32 attached in line to the studs S form a structure to which may be attached the panels of metal lathing 35 which are secured to the rods 32 preferably by tie wire 36. The lathing 35 is a wire mesh, the form illustrated being of the expanded metal lath variety. With the lathing in place the plaster 40 forming the finished wall may be applied. In the form illustrated in FIGS. 1 to 3 the resilient clips 10 haveflange portions 15 whichare somewhat longer than one-half the width of the studs S and in this case the clips 10 of the opposite walls of the double partition are staggered vertically with respect to each other so as not to interfere.

An alternative and somewhat cheaper method of attaching the clip 10 to the stud S is shown in FIG. 4in which-tie wire W is substituted for the bolt B, with the clip 10 lying in the same relative position against the stud S.

In FIG. '5- another alternative method of attaching the clip to the stud is shown in which the clip 10 is snapped or clipped onto the flange 4 of the stud S with the flange portion 15 and the backing portion 16 lying inside the corner formed by the web 3 and the flange 4-of the stud 8. As above described the first intermediate portion 18 of the clip 10 lies closely adjacent to backing portion .16 and forms therewith a spring clamp which is capable of receiving and gripping the flange 4 of the stud S and as shown in FIG. 5, with the flange 4 of thestud S lying between these parts, the clip 10 and associated structure are supported by the stud S'in an even more eco- 3 nomical and rapid method of attachment, which is satisfactory for some applications.

In FIG. 6 the resilient clip 10 of FIGS. 1 to is shown as used in combination with a wooden stud S2 of the common two by four variety, having a flat vertical wide face 45 and a flat vertical edge face 46 at right angles to the face 45. In this arrangement the clip is placed against the stud S2 with its flange and backing portions and 16 abutting the stud faces 45 and 46 and is secured to the stud S2 by nails N which are driven through additional holes 50 which are prefashioned in the flange 15 of the clip 10 for this alternative purpose.

Thus the clip of FIGS. 1 to 6 is provided with a number of alternative means for attachment to various sizes and types of wall studding which gives it a desirable adaptability and adjustability according to design requirements. By its ability to be attached inside or outside the edge corner of the steel stud S with the backing portion 16 either abutting the inside surface or the outside surface of flange 4 of the stud S, a range of adjustability is provided in the distance between the reinforced plaster wall 40 and the supporting stud 50 for flexibility and comprise between maximum room space and the accomodatlilon of vents, pipes and closets and the like within the wa It will be seen that the successive bends in the metal strip which forms the clip of the invention are formed in alternatively opposite directions and that the length of the successive portions 16, 18 and 20 are arranged so that in the preferred form, the rod receiving portion 23 lies on or near the plane of the flange portion 15.

While the resiliency is provided throughout the length of the clip, the greatest portion of the resiliency is pro vided by the bends 19 and 21.

While some variation in characteristics is allowable in the various bends and parts of the clip, the general form illustrated is preferred, in which the bend 21 has a larger diameter than any of the other bends, and in which the bend 24 of the rod receiving portion accomodates the pencil rod used with it and the rod receiving portion has the inwardly turned portion 25 which prevents the rod 32 from escaping. 7

FIGS. 7 to 11 show another embodiment of the clip and installation of the present invention comprising a clip 10a which corresponds generally in shape to clip 10 of FIGS. 1 to 6 except for the following:

(1) Backing portion 16a (corresponding to 16 in FIGS. 1 to 6) extends from bend 19a (corresponding to 19 in FIGS. 1 to 6) toward the first intermediate portion 18a (corresponding to 18 in FIGS. 1 to 6), to form with 18a a clip which firmly grips the flange 4 of stud S, as shown. This is accomplished by making bend 19a slightly more than 180 degrees.

(2) Instead of having the. elongated flange 15 (with slot and holes 50), as shown in FIGS. 1 to 6, the clip 10d has a short flange stub 15a formed by the bend 17a (corresponding to 17 in FIGS. 1 to 6) which extends at an angle of substantially 90 degrees from the portion 16a so that when the clip is installed as shown in FIGS. 7 to 11 with the flange 4 clipped between 16a and 18a the flange stub 15a abuts against the web portion 3.

(3) The member 25b which forms with the second intermediate portion 20a a channel 24b for receiving the pencil rod 32 to hold the rod is corrugated or sinuous in shape and is provided with a pair of staggered notches 25c in the opposite edges thereof, as shown in FIGS. 7, 10 and 11, which may be used for securing the rod 32 to the outer surface of 2511 with the rod 32 located in the elongated depression 25d (FIGS. 10 and 11) extending along the width of 255 and formed in the outer surface by 'said sinuous or corrugated shape- Thus, the rod 32 may be secured to the outer surface of extension 25b. as

aforementioned by a wire 252, as shown in FIGS, wand 11," or alternately it' may be clipped in the channel 24b 4 formed between 25b and the second intermediate portion 20a, as shown in FIGS. 7 to 9.

(4) The inner surface of the extension 25b is also formed with the elongated depression 25 between the elongated depression 25d and the innermost rod receiving portion 23a. The pencil rod 32 may be located between and gripped by the bottom of the elongated depression 25f and the opposite surface of the element 20a rather than in end rod receiving channel 24b. This is particularly desirable if the diameter of the pencil rod is so great that it is difiicult to force it completely into the channel 24b.

(5) The second intermediate portion 20a extends from the substantially degree bend 21a (corresponding to 21 in FIGS. 1 to 6) at the end of the first intermediate portion 18a to a line which is substantially opposite to and parallel with the bend 19a, as shown, before it is bent back on itself at 24a so that bend 24a is opposite bend 19a and both bends lie in a plane which is substantially parallel to the web 3 of stud S.

Clip 10a is less expensive to manufacture than clip 10. It has the advantage that it can be installed very easily with a minimum of time and eflort merely by clipping it to the stud and inserting rod 32 in it. This eliminates the need for driving nails or attaching the clip to the stud by nuts and bolts or by wiring and also eliminates the necessity of attaching the rod to the clip by wiring, all of which are time consuming and consequently expensive in construction work.

One of the advantages of using clip 10a with the rod 32 tied to the outer surface of the extension 25b as shown in FIGS. 10 and 11, is that the rod and hence the lathing is spaced at a greater distance from the first intermediate portion 18a to provide additional furring or space to clear pipes, etc. without resorting to the use of bolting the clip 10 as shown in FIG. 2 to achieve the extra clearance.

[It is noted that the lengths of the first and second intermediate portions 18 and 20 in FIGS. 1 to 6 and 18a and 20a in FIGS. 7 to 11 are relatively long compared to the distance therebetween. This increases the resiliency of the clip in the direction perpendicular to the wall portions.

It is pointed out that bend 21a does not have to be exactly 180 degrees, but can be somewhat larger or smaller, so long as it is not so large as to detrimentally reduce resiliency of the clip in the direction perpendicular to the planes of walls 1 and 2,or so small as to detn'mentally reduce the minimum distance between the first and second intermediate portions. The sharpness of the bend 21a canalso vary considerably so long as the bend is not so gradual as to detrimentally increase the stiffness of the clip or so sharp as to detrimentally reduce the minimum distance between the first and second intermediate portions.

Greatly improved sound proofing and other acoustical properties of rooms divided by the wall construction of the invention results from the greatly increased resiliency provided in the connection'll) and 10a between the reinforced wall panels and the supporting studding S. This resiliency also increases the life of the plaster walls by reducing the tendency to crack as a result of shock and expansion and contraction and settlement of the building structure.

This application is a continuation-in-part application of United States patent application Serial No. 549,730, filed mediate portion formed by a substantially 18Q degree bend at the .end offthe backing portion opposite from the .end forming the substantially rightan'gle bend, said first-intermediate portion being spaced from said backing'po'rtion and extending along said backing portion beyond the plane of said end portion, a second intermediate portion formed by a substantially 180 degree bend at the end of the first intermediate portion opposite from the end thereof forming said first mentioned 180 degree bend, said second intermediate portion being spaced from and extending along the side of said first intermediate portion which is opposite the side thereof facing the backing portion, and a portion formed by a bend in the end of said second intermediate portion opposite from the end thereof forming said second 180 degree bend, said bend in said opposite end of said second intermediate portion being in a direction away from said end portion and defining a channel, said end portion having spaced nail holes and a bolt slot elongated in a direction transverse to said intermediate portions, said holes and slot providing alternate means for fastening said clip to said stud.
